Issue Unable to repair web server configuration due to AH00526: Syntax error on line 1 of /etc/apache2/plesk.conf.d/server.conf

[wesolveproblems]

Firstly, thank you in advance for your assistance!

I am unable to repair web server configuration due to AH00526: Syntax error on line 1 of /etc/apache2/plesk.conf.d/server.conf

This is really strange... First I got this error

New configuration files for the Apache web server were not created due to the errors in configuration templates: AH00548: NameVirtualHost has no effect and will be removed in the next release /etc/apache2/ports.conf:8 AH00526: Syntax error on line 1 of /etc/apache2/plesk.conf.d/server.conf: Invalid command '\xe2\x88\x91#ATTENTION!', perhaps misspelled or defined by a module not included in the server configuration . Detailed error descriptions were sent to you by email. Please resolve the issues and click here to generate broken configuration files once again or here to generate all configuration files. See the details in Configuration Troubleshooter.

I went to the config troubleshooter and I tried to search in KB which took me to a 404 http://kb.plesk.com/en/products/?id=52&qprod=52

So, I removed those comments from being generated by editing
/usr/local/psa/admin/conf/templates/custom/server.php to comment out //echo AUTOGENERATED_CONFIGS;

Now it seems to think that there is a "-" at the beginning of my /etc/apache2/plesk.conf.d/server.conf - but there isn't one!!

The first chars in that file are `ServerName` here is the error I'm getting when I run plesk repair web:

I was following this guide to remove the plesk fingerprints from my http headers and I think that this has something to do with the custom configs mentioned here:

Resolved - Server header

When I remove those custom configs, I am able to rebuild.

How can I safely remove x-powered-by: PleskLin from my http headers?
